This invention is really practical. After we usually buy a lot of things, it is really difficult to climb the stairs. After driving to the door, if the floor is high, you should lift it up bit by bit. But this invention directly solves the problems we encounter at present, and it is often inconvenient to get in and out when moving, or it is easy to damage the wall when moving. With the invention, the moving time can be saved, and the overall beauty of the house can be better maintained.
For some special people, this invention is simply timely rain, such as the elderly with inconvenient legs and feet. Nowadays, in many cases, the elderly live alone. Once they buy too many things, moving them upstairs is really a lot of work. Disabled people also need such a tool to help them realize things upstairs. Invention is to change according to the needs of life to facilitate our daily life. The appearance of elevator greatly facilitates these special people, so this invention is very useful. If the patent application is successful, it can also help this uncle make some money. I also hope that this kind of elevator can be installed in more houses to facilitate the daily needs of residents.
My uncle's name is Cui Junjie. He is 65 years old and has retired. In an interview with Jiupai News, he said that when he was young, he liked to tinker with gadgets. After retirement, he became more restless. Because his lumbar intervertebral disc is protruding, he can't lift heavy objects, so he wants to invent an elevator to lift things. Cui Junjie introduced that 36 sensors were implanted in the elevator, which cost more than 4,000 yuan, and the automation expertise involved was self-taught. I have taught myself automation knowledge for 8 years, including elevators, and I have 4 invention patents. ? Damn, this invention has practical significance. With so many patents applied, it will definitely be realized.
